How can a person learn to stop wanting to meet anyone anymore?

I'm a gay guy in my mid 20s who's still a virgin. I've tried pretty much everything for years and have been rejected by every guy I've approached.

It hurts because I keep seeing other people living the kind of life I wish I could have. At this point I want to learn how to stop wanting sexual encounters or relationships with other guys altogether. How can I do that?

Please don't ask me what happened or why I got rejected. I’m simply not desired by anyone. It already hurts enough as it is and I don't want to get into the details.
